Additionally, surge protection is promoted through the use of surge arresters (11), also called metal oxide varistors (MOVs).
Description
- This invention relates to energy saving devices, more particularly, an energy savings device with surge protection which may provide selectable periods of correction to optimize reduction in energy usage over expected periods of high or low energy demand.
- In residential or commercial establishments, the loads served by electric utility companies are generally primarily resistive, such as a space heater, or primarily inductive, such as a motor. The inductive loads draw a combination of kilowatts (real or inductive power) and kilovars (reactive power). Capacitors are a static source of kilovars.
- Capacitors installed at inductive loads provide a number of benefits: reduced electrical energy consumption, reduced line current, increased voltage at the load, better voltage regulation and lower energy losses. These benefits are accomplished by installing sufficiently sized capacitors at the load to bring power factor to just under unity. Power factor is equal to killowatts divided by kilovars.
- Unfortunately, capacitors are not used to optimize load factor as widely as they might be. This is especially true in residential and commercial applications. One reason for the latter is that current devices do not allow for any periods of correction to optimize reduction in energy usage over periods of high or low energy demand. Currently, energy saving devices use capacitors with fixed levels of capacitance, commonly measured in microfarads (mF). The size of a capacitor to be used in any residential or commercial application is determined by the average energy usage at the time of installation. However, this method of determining the required capacitance does not take into account periods of high or low energy demand. As a result, during periods of high energy demand, the capacitor may not be large enough to achieve the optimal reduction in kilowatt usage. Alternatively, during periods of low energy demand, the energy used to power the capacitor may offset any energy savings.
- Thus, a need exists for an energy savings device which provides the user with selectable periods of correction to optimize reduction in energy usage over expected periods of high or low energy demand.

Upon installation thefront cover 3 may be secured to theouter enclosure 2 usingscrews 20, rivets, etc. to prevent unapproved access to the unit.Surge arresters 11 located inside theouter enclosure 2 provide surge, lightning, and brown-out protection by consistently supplying appropriate voltage load. The number ofsurge arresters 11 depend on the electrical demand of an application. At least onecapacitor 10 is located inside of theouter enclosure 2. The number and capacitance level measured in microfarads of thecapacitors 10 in theunit 1 depend on the electrical demand of an application and if the application is a single-phase or three-phase application. At least one on/off switches/button 6 may be for manually activating and deactivating the at least onecapacitor 10 during periods of high or low energy consumption is located on theinner cover 4 of theouter enclosure 2. When aunit 1 has more than one capacitor, as shown inFIG. 3 , multiple on/off switches/buttons 6 may be used for individually activating and deactivating thecapacitors 10 to achieve various capacitance levels. - Three indicator lamps may be located on the
front cover 3. A capacitor on/offindicator lamp 7 indicates whether thecapacitors 10 are activated or deactivated, apower indicator lamp 8, preferably amber, indicates that electricity is being supplied to theunit 1, and ahazard indicator lamp 9, preferably red, indicates if theunit 1 is not functioning properly. Theunit 1 may be connected to an electrical service at the breaker box in any single phase or three phase service. - Referring now to
FIGS. 4 and 5 , a second embodiment of the invention is shown in which theunit 1 uses at least onevariable capacitance capacitor 13 in place of astandard capacitor 10 having a fixed level of capacitance. The number ofvariable capacitance capacitors 13 in theunit 1 depend on the electrical demand of an application and if the application is a single-phase or three-phase application. -
FIG. 6 shows a wiring diagram of the invention having asingle capacitance capacitor 10 withtaps 16 electrically connected to a bank ofsurge arresters 11 with an on/offswitch 6 and a capacitor on/offindicator light 7. - As further shown in
FIGS. 7 and 8 , thevariable capacitance capacitor 13 is made up of multiple discreetcapacitive cells 15 separated from each other and having individual taps 16 or acommon terminal 17. Each discreetcapacitive cell 15 has a fixed capacitance level. The individual taps 16 allow the user to individually activate and deactivate each discreetcapacitive cell 15 through the use of activator switches/buttons 21,timers 12 and/ormeters 18 to achieve various levels of capacitance without the use of multiple standard capacitors with fixed levels of capacitance.

Alternatively, the multiple discreetcapacitive cells 15 may all be deactivated at the same time when no power correction is needed. The level of capacitance may be displayed on the outside of the unit with the use ofcapacitance indicator lamps 19. Thediscreet capacitive cells 15 may also be controlled through the use of a servo-loop control 14 which actively monitors power consumption and automatically activates or deactivates discreetcapacitive cells 15 so as to change the level of capacitance according to the energy demand at any given time. - Referring now to
FIG. 9 , a third embodiment is illustrated in which atimer 12 located inside theouter enclosure 2, provides the option of programing theunit 1 with multiple start and stop times for activating and deactivating thecapacitor 10 depending on periods of high or low energy demands. For example, in a commercial setting, thetimer 12 may be programmed to activate thecapacitor 9 during a business' hours of operation when there is a high energy demand and programmed to deactivate thecapacitor 10 while the business is closed and when there is a low energy demand. - In addition, as shown in
FIG. 10 , thetimer 12 may be programmed to individually activate and deactivatemultiple capacitors 10 or multiple discreetcapacitive cells 15 ofvariable capacitance capacitor 13 to achieve various capacitance levels at different times. - As shown in
FIG. 11 , a forth embodiment of the invention uses ameter 18 to measure energy usage and automatically activates and deactivates thecapacitor 10 or multiple discreetcapacitive cells 15 ofvariable capacitance capacitor 13 to achieve various capacitance levels depending on the energy demand at any given time. - It is to be understood that while a preferred embodiment of the invention is illustrated, it is not to be limited to the specific form or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not be considered limited to what is shown and described in the specification and drawings.
